show lacp system-identier
Displays the LACP system identier for a device.
Syntax
show lacp system-identifier
Parameters None
Default Not congured
Command Mode EXEC
Usage Information The LACP system ID is a combination of the congurable LACP system priority value and the MAC address. Each
system that runs LACP has an LACP system priority value. The default value is 32768 or congure a value
between 1 and 65535. LACP uses the system priority with the MAC address to form the system ID and uses the
system priority during negotiation with other devices. A higher system priority value means a lower priority. The
system ID is dierent for each device.

Link Layer Discovery Protocol
Link layer discovery protocol (LLDP) enables a local area network (LAN) device to advertise its system and receive system information
from adjacent LAN devices.
• LLDP is enabled by default on OS10 interfaces.
• An LLDP-enabled interface supports up to eight neighbors. An OS10 switch supports a maximum of 250 neighbors per system.
• OS10 devices receive and periodically transmit Link Layer Discovery Protocol Data Units (LLDPDUs), which are data packets. The
default transmission interval is 30 seconds.
• LLDPDU information received from a neighbor expires after the default time to live (TTL) value of 120 seconds.
• Spanning-tree blocked ports allow LLDPDUs.
• 802.1X-controlled ports do not allow LLDPDUs until the connected device is authenticated.
• Link layer discovery protocol-media endpoint discovery (LLDP-MED) is enabled on all interfaces by default.
Protocol data units
LLDP devices exchange system information represented as type, length, and value (TLV) segments:
Type
Information included in the TLV.
Length Value in bytes of the TLV after the Length eld.
Value System information the agent advertises.
